In ΔABC, AB=AC and h is the altitude from A to BC. Given, area of ΔA – InterviewSolution

1.	In ΔABC, AB=AC and h is the altitude from A to BC. Given, area of ΔABC is A, and perimeter P=2(√2hr−h2+√2hr), where r is the circumradius of ΔABC, then 1rlimh→0AP3=
Answer» In $Δ A B C, A B = A C$ and $h$ is the altitude from $A$ to $B C$ . Given, area of $Δ A B C$ is $A$ , and perimeter $P = 2 (\sqrt{2 h r - h^{2}} + \sqrt{2 h r})$ , where $r$ is the circumradius of $Δ A B C$ , then $\frac{1}{r lim h \to 0 \frac{A}{P^{3}}} =$
